Dr. Stolar is a fantastic, dedicated and thoughtful doctor. When you’re with him you know he’s listening for the bigger picture and the important details. Highly recommend. A patient couldn’t do better!

Dr Stolar is a great listener which then leverages into his ability to provide the best care possible. He works with his patients to assess how to administer care. For instance, if the person wants to avoid a pharm solution, he will help find another alternative where possible. He is very trustworthy.

I highly recommend Dr. Stolar to anyone with endocrine issues (e.g., thyroid, diabetes, hormones). He is knowledgeable and compassionate and he treats the whole person. He's been my physician for 16 years and he's the only doctor who has ever made me feel better as a result of seeing him.

Really understands the psychology behind being diabetic. Gives good advice that is actually applicable to real life as a diabetic. Does not berate you for having high numbers, instead works with you to make lifestyle changes. Gets very excited for you when your numbers improve. Definitely an "above and beyond" doctor.

Dr. Stolar considers my time restraints and ALWAYS fits me in to his schedule when I am ill. He is extremely knowledgeable and always knows the answers to my symptoms OR refers me to a specialist out of his field. Most importantly, he doesn't have his hand on the door knob when I am in his care. He LISTENS to why I am there and thoroughly treats my symptoms. He has a wonderful bedside manor & I give Dr. Stolar the highest recommendation.

Pleasant, aasy to speak to, attentive, thoughtful in his responses, considerate of patient perspective, asks a lot of questions to get down to the root of the problem, no unnecessary procedures/tests

I have been going to Dr. Stolar for about 15 years and I have always received excellent care. The practice is very busy but Dr. Stolar always takes time to listen to what you tell him and take everything into consideration. He is an easy doctor to talk to which is a rare thing these days.

He has been my primary care physician for 30 years! He is an excellent physician, thorough in physical assessment, listens carefully to his patients and makes a plan to fit them.

Dr Stolar is very knowledgeable but he is also willing to listen to you and work out a treatment plan that's realistic. I love that he has a great sense of humor and doesn't rush through the visit.
